N0. 19,800. Patented Mar. 30,1858.

UNITED STATES PATENT OFFICE.

WM. J. STEVENSON, OF NEW' YORK, N. Y.

MACHINE FOR SHELLING- PEAS.

Specification of Letters Patent No. 19,800, dated March 30, 1858.

To all whom it may concern:

Be it known that I, IVILLIAM J. STEVEN- SON, of the city, county, andState of New York, have invented a new and useful Machine fo-r ShellingPeas; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the annexeddrawings, making a part of this specification, in which Figure 1, is aside sectional elevation of my improvement. Fig. 2, is a plan or topview of ditto. Fig. 3, is anenlarged transverse section of the rollersand a portion of one of the endless cords showing clearly the operationof the above parts.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in the employment or use of rollers inconnection with a series of endless cords, arranged substantially ashereinafter shown whereby the peas may be shelled and separated fromtheir pods with the greatest facility.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A, represents a rectangular ,box in the lower part of which a drawer B,is placed transversely, and C, D, are two rollers which are placedtransversely at one end of the upper part of the box. At the oppositeend of the box a roller E, is placed. The rollers D, E, are placed inthe same horizontal plane and endless cords F, pass around them. Thesecords extend the whole width of the box and are placed at equal andsuitable distances apart, see Fig. 2. The cords may be constructed ofsilk, hemp or any suitable material and the front roller D, may begrooved circumferentially to keep the cords in proper position and alsoto serve as a protection to the same. The rollers D, E, have theirjournals fitted in bearings which are capable of being adjustedhorizontally by set screws (a). The roller C, is placed over the rollerD, but the two rollers are in an inclined plane that is to say, theroller C, is placed a little farther inward or toward the roller E, thanthe roller D. The ournals of the roller C, are fitted in bea'rings whichare rendered capable of verticaladjustment and whichmay be secured atany desired point by set screws (1)).

On each end of the roller E, a cam G, is placed, and on-these cams theinner end of a hopper H, rests. The hopper H, is placed in a slightlyinclined position and is pivoted near its outer end to horizontal armsor projections (0), (c), at the upper part of the box A.

The operation is as follows: The peas to be shelled, shown in red areplaced in the hopper H, and the roller D, is rotated in the directionindicated by the arrow by any proper means. The hopper is vibratedvertically by means of the cams G, G, and the peas are fed thereby fromthe hopper on the endless cords F, which convey the peas to the rollersC, D. The pods as they pass underneath the roller C, are depressed orforced down, the cords F, yielding and the pods will be split by thepressure and will be caught in the bite of the rollersand as the podsare drawn between the two rollers C, D, the peas will be stripped fromtheir pods and owing to the position of the roller C, relatively withthe roller D, the peas will be forced downward between the cords F, intothe drawer B. The operation of the rollers C, D, is clearly shown inFig. 2. It will be seen that the peas are stripped from the pods andrepelled by the rollers in consequence of the obtuse angle formed by thebite, and as the pods are split they are compressed so that they will becaught in the bite of the rollers, while the peas, for the reason abovestated will be repelled from them and forced down between the cords intothe drawer B.

This machine has been practically tested and operates well. It willprove highly valuable where peas are raised in large quantities, andform a staple crop.

I would'remark that it is perfectly immaterial as regards the way thepods are presented to the rollers C. D. Those pods that are presentedsidewise are split and have the whole number of peas they contain forcedfrom them at once, whereas those that are presented endwise will havetheir peas forced from them consecutively as the.

pods are drawn between the rollers C. D. The implement will shell eithergreen or dried peas.

I do not claim separately and broadly the employment or use of rollers,as separators for they have been previously used for such purposes, asfor instance in the roller cotton gin, where the seed is stripped fromthe cotton by the same process as herein described. Neither do I claimbroadly the employment of the rollers with an endless belt or carrierirrespective of the construc and endless cords F, arranged to operatetion of the same, and its arrangement with substantially as and for thepurpose herein 10 the rollers, whereby the apron serves as a set forth.carrier for the pods and allows the shelled 5 peas to pass through it.STEVENSON What I claim therefore as new and desire Vitnesses: I tosecure by Letters Patent is, v W. TUsoH,

The combination of the rollers C, D, E, W. HAUFF. a
